How do endocrinologists perform the test that confirms hypoglycemia?

72 hour fast: If they are looking for an Insulin producing tumor ( insulinoma), you may be asked to fast for a maximum of 72 hours. If and when you develop hypoglycemia during that time, labs will be drawn to determine the cause.
